Worst airline in South Africa

If a callcentre agent tells you that it will be so much to change your flight and you make arrangements for work and when you phone again to change and they tell you more than a R1000 more than the original price quoted now there must be an issue! And when you ask to speak to the manager he send a message 'it wont help he speaks to me, cause the procesure will still be the same' now that is called incompatance! I fly all over the world and have never dealt with such uselesness! I will in future rather pay more at another ailine like kulula or british airways or any other to get better service then the pathetic service they give! Do not fly Mango they are extremely bad and dont even want to listen to complaints
